The aforementioned charts delineate the share of two types of population, the former-utilizing public transport, and the latter-using private motor vehicles in five cities, located in Australia continent from 2000 to 2010.
At the first glance it is clearly seen that in the whole period of time, the number of people who used public transport was relatively stable in all four countries, excluding Sydney, who witnessed a sharp escalating growth. Meanwhile, the share of citizens, utilizing thier own mean of transport maintained a consistent trajectory in three cities, except two cities, where the quantity of car owners experienced a slightly fluctuating behaviour.
In the beginning of the period the Adelaide was a nadir of the dataset, reaching only 5% of people who used public transport and maintained the same position until the 2010’s year, having a lowest percentage of this type of individuals. Brisbane, which population’s percentage was 15% and held the middle position among other countries in 2000, had a stable behaviour in the period from 2000 to 2002, and then experienced a dramatic surge in 2006, peaking at 25%. Until the end of the period, it witnessed a slight growth and finally reached at roughly 27%. Sydney’s population, which had a dominating position at the start ended, ranking the second among all cities.
In 2000, Adelaide’s citizens, owning car, were the highest in percentage among other cities, hitting just over 70% and experiencing a steady grow over the whole period and culminating at 90% in 2010. In contrast, Perth and Brisbane, held a consistent trajectory all years, witnessing only a insignificant growth by 10% both, reaching 60 % and 50% in the end, respectively. Melbourne and Sydney, that had 30% and 20% at the start, respectively, exhibited a intermittent volatility throughout the whole period and reached roughly the same position in 2010.
